Space Shuttle Discovery Launch Rescheduled For Tomorrow, NASA Says

At 4:30 p.m. ET, NASA will hold a news conference in Florida, to announce a new launch time for STS-128, the Space Shuttle Discovery's mission to the International Space Station. (It has been postponed twice, because of inclement weather and a faulty fuel valve.)

NASA managers hope to start the launch countdown at 8:34 a.m. ET on Friday, for an 11:59 p.m. ET takeoff.

Discovery will take the Leonardo supply module to the International Space Station. Astronauts will attach it to the Harmony node.

NASA has planned only seven more shuttle missions, including this one.
